UN DIENTE EXCAVADOR A ACOPLAR EN EL FILO EXCAVADOR DE UN EQUIPO DE EXCAVACION QUE COMPRENDE UN MIEMBRO DE DESGASTE (12) CON UNAS SUPERFICIES DE SOPORTE (67, 68, 72) DISPUESTAS EN UN ZOCALO QUE SE EXTIENDEN SUSTANCIALMENTE EN PARALELO AL EJE LONGITUDINAL DEL DIENTE. LAS SUPERFICIES DE SOPORTE ESTAN FORMADAS DE MODO QUE SE ENSANCHEN SIGNIFICATIVAMENTE CONFORME SE EXTIENDEN HACIA LA PARTE DE ATRAS PARA FORMAR UNAS SUPERFICIES DE SOPORTE DE TABLEROS EN LOS EXTREMOS POSTERIORES (84) DEL MIEMBRO DE DESGASTE. LAS SUPERFICIES DE SOPORTE ESTAN DISPUESTAS ENTRE UNAS PAREDES CONVERGENTES (78, 79) Y UNAS PAREDES LATERALES (74, 75) DEL ZOCALO EN ANGULOS OBTUSOS A LAS MISMAS PARA EVITAR QUE SE FORMEN ZONAS DE CONCENTRACION DE ESFUERZOS. EL MIEMBRO DE DESGASTE SE ASEGURA TAMBIEN A UN ADAPTADOR A TRAVES DE UNOS FIADORES PARA FACILITAR EL MONTAJE Y DESMONTAJE DEL MIEMBRO DE DESGASTE. The invention describes an extensible lock (14) for securing a wear member (12) to an adapter nose (13) for an excavating tooth, said lock comprising a body (92), a base (90) coupled to said body to form an assembly adapted for insertion into a hole (103) in the adapter nose, and means (96) for selectively adjusting the relative axial positions of said body and said base between an extended position for securing the wear member to the adapter nose and a retracted position for releasing the wear member from the adapter nose, said body including a bearing face (122) for engaging in the wear member in the extended position.
